UL’s Improved Code Correlation Database

Does UL have a version of the Code Correlation Database that is optimized for a smart phone?

 Yes. UL has redesigned the Code Correlation Database available on the Code Authorities page of UL.com so it’s easily accessed at www.ul.com/codelink from any Internet-connected device. The database has been redesigned to a responsive, user- friendly format for any screen size from smart phone to desktop computer.

The database currently includes 18 model codes that have been correlated to identify the UL product category and a list of certified products for each code section. This enables you to select a code section and find the UL Certified (Listed) products that can be used for that installation. In addition to links to the UL Guide Information and list of UL Certified (Listed) products, the results page also provides a link to the scope of the UL Standard used to certify (List) a product as well as links to other UL information applicable to the type of products such as UL marking and application guides, UL newsletter articles and UL evaluation reports, all in one place.

The 2014 NEC expanded the requirements for arc-fault circuit interrupter (AFCI) protection to include kitchens and laundry areas of dwellings that also require ground-fault circuit interrupter (GFCI) protection for receptacles. Does UL Certify (List) dual function AFCI/GFCI circuit breakers?

 Yes. UL certifies (Lists) dual function, Combination AFCI and GFCI circuit breakers under the product category Circuit Breakers with Ground-fault Circuit Interrupter and Combination-type Arc-fault Circuit Interrupter Protection (DIYG). This product category can only be viewed online at UL’s Online Certifications Directory at www.ul.com/database (enter DIYG at the

category code search field). Presently, there are at least two manufacturers with Certified (Listed) dual function AFCI/GFCI circuit breakers.

This category covers circuit breakers incorporating ground-fault circuit interrupter (GFCI) and combination-type arc-fault circuit interrupter (AFCI) protection. These devices are designed to provide overcurrent protection; protection against shock hazard; and protection of either or both branch-circuit wiring and feeder wiring, as well as cord sets and power-supply cords connected to receptacles against the unwanted effects of arcing. They are intended for use where both GFCI and combination-type AFCI protection is required by the National Electrical Code (NEC), ANSI/NFPA 70.

Intended to be installed in new or existing service equipment, panelboards, and similar products, these devices provide Class A ground-fault circuit interrupter protection and are intended for use only in grounded 60 Hz alternating-current systems where Class A GFCI protection is required in accordance with the NEC.

A two-wire device is unsuitable for use in a multiwire branch circuit as defined in the NEC. Some devices rated 120/240 V lack a load neutral wire connector and are intended for use with 208 V or 240 V loads only. Devices with markings other than  “Line” and  “Load” are suitable for operation with a supply source connected to either side.

The UL Certification (Listing) Mark on a device will include one of the following product identities that can be read while the device is installed and with a dead-front removed:

CB/GFCI/Combination AFCI or Circuit Breaker/Ground-fault Circuit  Interrupter/Combination Arc-fault Circuit Interrupter

These devices are evaluated for compliance with ANSI/UL 1699, the Standard for Safety of Arc-Fault Circuit Interrupters; ANSI/UL 943, the Standard for Safety for Ground Fault Circuit Interrupters; and ANSI/UL 489, the Standard for Safety for Molded Case Circuit Breakers, Molded-Case Switches and Circuit-Breaker Enclosures.
